Die Erfindung betrifft einen Extruder zum Herstellen eines zweifarbigen Stranges mit zwei koaxial ineinander angeordneten, je einen Schneckengang aufweisenden Schnecken zum Zuführen unterschiedlicher plastischer Massen über je einen Förderraum zu einem Mundstück und mit einem Einfülltrichter zum Zuführen der Massen zu dem Schneckengang der hohlzylinderförmig ausgebildeten, antreibbaren äußeren Schnecke sowie über im Bereich des Einfülltrichters angeordnete Durchbrüche in der Umfangswand der äußeren Schnecke zu dem Schneckengang der inneren Schnekke. The invention relates to an extruder for manufacturing a two-tone strand with two coaxially arranged one inside the other, each having a screw thread Screws for supplying different plastic masses to one each via a conveying space Mouthpiece and with a funnel for feeding the masses to the screw thread of the hollow cylinder-shaped trained, drivable outer screw and arranged in the area of the hopper Breakthroughs in the peripheral wall of the outer worm to the worm thread of the inner worm.
Ein bekannter Extruder dieser Art eignet sich zum Zusammenführen zweier, über getrennte Aufgabetrichter eingespeister Massen (OE-PS 1 98 501). Wesentlicher Zweck des bekannten Extruders ist das Vermeiden der unerwünschten und zu Störungen führenden Rückwärtsbewegung der Massen zwischen der Innenwandung der äußeren Schnecke und der Außenwandung der inneren Schnecke.A known extruder of this type is suitable for merging two via separate feed hoppers masses fed in (OE-PS 1 98 501). The main purpose of the known extruder is to avoid the undesired and disruptive backward movement of the masses between the inner wall the outer scroll and the outer wall of the inner scroll.
Mit dem bekannten Extruder kann ein zweifarbiger Strang extrudiert werden, dessen mehr oder weniger dicke Hülle aus der Masse besteht, welche die äußere Schnecke fördert, während der Kern des Stranges aus der Masse gebildet ist, welche die innen liegende Schnecke fördert. Der bekannte Extruder ist deshalb dann verwendbar, wenn ein zweifarbiger Strang mit einer marmorähnlichen Struktur hergestellt werden soll, aus welchem dann beispielsweise Seifenstücke geprägt weiden sollen. Hierbei muß nämlich die Marmorierung den ganzen Strang gleichmäßig durchsetzen, und es dürfen sich keine größeren einfarbigen ZellenWith the known extruder, a two-colored strand can be extruded, its more or less thick shell consists of the mass that the outer screw conveys, while the core of the strand consists of the mass is formed, which promotes the internal screw. The known extruder is therefore Can be used when a two-tone strand with a marble-like structure is produced should, from which then, for example, bars of soap should graze embossed. The marbling has to be done here uniformly penetrate the whole strand, and there must not be any larger, single-colored cells
ausbilden. .form. .
Die Aufgabe bestand deshalb dann, den bekannten Extruder so zu verbessern, daß ein Strang mit über dessen ganzen Querschnitt gleichmäßig verteilter marmorähnlichen Struktur hergestellt werden kann, de^ dann zu homogen marmorierten Seifenstücken weiter verarbeitet werden kann.The task was then to improve the known extruder so that a strand with over it whole cross-section of evenly distributed marble-like structure can be produced, de ^ then can be further processed into homogeneously marbled soap bars.
Die Lösung dieser Aufgabe besteht bei einem Extruder der oben beschriebenen Art darin, daß der Schnekkengang der äußeren Schnecke in seiner Steigungsrichtung entgegengesetzt zu dem Schneckengang der feststehend angeordneten inneren Schnecke verläuft und daß die äußere Schnecke an ihrem dem Mundstück zugewandten Endabschnitt einen Mischring mit in den ringförmigen Förderraum der inneren Schnecke sowie in den ringförmigen Förderraum der äußeren Schnecke ragenden Mischflügeln zum Vermischen des Stranges zu einer marmorähnlichen Struktur trägt.The solution to this problem is an extruder of the type described above in that the worm gear of the outer worm is in its direction of pitch runs opposite to the screw flight of the stationary inner screw and that the outer screw at its end portion facing the mouthpiece with a mixing ring in the annular conveying space of the inner screw as well as in the annular conveying space of the outer screw protruding mixing blades for mixing the strand into a marble-like structure.
Durch die gegenläufige Steigungsrichtung der Schneckengänge der äußeren und der inneren Schnekke wird eine problemloses Fördern der beiden unterschiedlich gefärbten Massen durch den Extruder sichergestellt. Die Förderung mittels der äußeren Schnecke erfolgt durch deren Rotation mittels eines Antriebs. Demgegenüber wird bei der feslehenden inneren Schnecke die Förderung der Masse durch die innere Wand der hohlzylindrisch ausgebildeten äußeren Schnecke bewirkt.Due to the opposite pitch direction of the screw threads of the outer and inner screws a problem-free conveyance of the two differently colored masses through the extruder is ensured. The conveyance by means of the outer screw takes place through its rotation by means of a drive. On the other hand, in the case of the defying inner screw, the conveyance of the mass is achieved through the inner one Wall of the hollow cylindrical outer screw causes.
Eine zweckmäßige Ausgestaltung des Gegenstandes der Erfindung besteht darin, daß die innere Schnecke Kühlmittel-Bohrungen und mit dem Förderraum der inneren Schnecke in Verbindung stehende Bohrungen zur Einleitung von flüssigen Zusatzstoffen aufweist.An expedient embodiment of the subject matter of the invention is that the inner screw Coolant bores and bores connected to the conveying space of the inner screw for introducing liquid additives.
Durch die Kühlmittel-Bohrungen kann Kühlmittel, beispielsweise Kühlwasser, geleitet werden, wodurch reibungsbedingte Wärme aus dem Extruder abgeführt werden kann. Weiterhin können durch die Bohrungen in der inneren Schnecke, durch welche flüssige Zusatzstoffe, das sind in der Regel Farbstoffe, in die von der inneren Schnecke geförderte Masse geleitet werden.Coolant, for example cooling water, can be passed through the coolant bores, as a result of which friction-related heat can be removed from the extruder. Furthermore, through the holes in the inner screw, through which liquid additives, which are usually dyes, are introduced by the inner screw conveyed mass.
Durch die erfindungsgemäße Anordnung eines Mischringes am dem Mundstück zugewandten Endabschnitt der äußeren Schnecke wird eine gewisse Vermischung der beiden Massen bewirkt. Die Zahl der an dem Mischring angeordneten Mischflügel richtet sich nach dem angestrebten Grad der Vermischung. Zur Erzielung einer ausgeprägten und den Strangquerschnitt homogen durchsetzenden marmorähnlichen Struktur empfiehlt es sich, etwa 6 bis 10 Mischflügel vorzusehen. Die rotierenden Mischflügel fördern sowohl Teilchen aus der von der inneren Schnecke geförderten Masse in die von der äußeren Schnecke geförderte Masse als auch umgekehrt. Hierdurch wird verhindert, daß sich in dem Strang Bereiche ohne marmorähnliche Struktur ausbilden.The inventive arrangement of a mixing ring on the end section facing the mouthpiece the outer screw causes a certain mixing of the two masses. The number of at The mixing paddle arranged on the mixing ring depends on the desired degree of mixing. To achieve a pronounced marble-like structure that homogeneously penetrates the strand cross-section it is advisable to provide about 6 to 10 mixing blades. The rotating mixing blades convey both particles from the mass conveyed by the inner screw into the mass conveyed by the outer screw as also vice versa. This prevents areas without a marble-like structure in the strand form.
